-9. (canceled)
A capsule for containing a powdered preparation, capable of receiving a pressured liquid, comprising an external casing and a composite film inside, characterized by said composite film comprising at least two films of different materials, adjacent and superimposed, in which:
- film is capable of receiving various markers, previously indented, wherein said markers present at least four configuration types:
- different geometries with different thicknesses;
- different geometries with the same thicknesses;
- equal geometries with different thicknesses;
- bursting of film, when it is subject to a given pressure of the fluid, is undertaken by phases at markers, capable of defining flow channels with the desired size and orientation;
- bursting of the composite film, in the cases it presents thicknesses, starts at the film, essentially at the zones where the surface has been more worn, and successively along the whole pre-defined profile of wear;
- the bursting of film is initiated as a consequence of the bursting of film, at the same place which were previously subject to indentations of film.
A capsule for containing a powdered preparation, according to claim 1, the various indentation topographies used permitting to vary the extraction flow, the pressures, the contact time of the fluid and the preparation, the texture, density and presentation of the final product.
